As young PR and communications professionals, we are often expected to know everything about social media. That is why, this week on Young PR Pros our hosts Kristine D'Arbelles and Julia Kent talk about the most popular social networks, who uses them, and what companies might benefit from each platform.

The main lesson we want listeners to take away from this episode is that it doesn't matter if 1.5 billion or 300 million people are using a social network - doesn't mean your company NEEDS to be there. As a young professional entering a new job, make sure you ask your executives and your bosses what their business goals are.

And remember, if you are using social networks to build your professional brand you have your own business goals.
